Failed to prune

[erikguo]

Hello,

I build your darknet by build.sh successfully. Then I use 'darknet prune' command to prune my yolo3-spp. But I always failed when calculating pruning to layer 76.

Do I miss some thing ?

Thank you for your help

thank you. I will check this fault tomorrow.

@gmayday1997 when the layer conv-->max pool->route, the conv layer need net.layers[i+1] & net.layers[i+2], net.layers[i+2] is route layer, net.layers[i+2].biases is null, prune may make some mistake.

@erikguo @anhuipl2010 thanks for pointing this. I have fixed this bug, and it works well now. If you want to prune more parameters, you can set -shuffle equal 1, which means random pruning. On the basis of my experiment results, there is really little gap between random pruning and bn-scale pruning.

./darknet prune ./cfgfile ./weightsfile -rate 0.4 -shuffle 1

@gmayday1997 u are handsome. do u add sparsity train code for the last update?

@gmayday1997 your code fopen() function in prune, maybe take some mistake. maybe you can changed it to fopen("xxxx", "wb"); or fopen("xxxx", "w");

@anhuipl2010 thanks, I fixed that. :smile: :blush:

@erikguo can you please let me know how you installed this repo.

I git cloned this repo, 1) make clean 2) make 3) sh build.sh
